LIQUID-SPRAYER.

SPECIFICATION forming part of Letters Patent No. 653,333, dated July 10,1900. Application inea January 1900. serai No. 537. (No man.)

To oaZZ whom t may concern.'

Be it known that I, VLnwrs AUGUSTUS As- PINWALL, a citizen of the UnitedStates, residing at Jackson, in the county of Jackson and StateofMichigan, have invented an Improvement inLiquid-Sprayers, of which thefollowing is a specification. i

My invention relates to a liquid-spraying device mounted on wheels andadapted to be moved about from place to place, especially through alield of potatoes for spraying the rows of plants with a liquid solutionof parisgreen or similar poisonous material for killing potato-bugs orother insects.

In carrying out my invention the water is contained in a barrel orreceptacle mounted on the frame of the vehicle, and the Water isconveyed from said receptacle by a pipe to a pump the plunger of whichis operated by suitable devices from the axle of the vehicle as the samerevolves. From the pump the water is passed to an air-chamber and fromthence beneath a receptacle holding parisgreen or similar poisonousmaterial, in which pressure is applied to the contents to force the sameinto the flowing stream of water, the mixture .then passing throughflexible pipes and connections to adjustable spraying-nozzles to bedelivered on the-plants.

The operations of the devices and also of the adjustablespraying-nozzles are effected by the operator, for whom a seat isprovided on the vehicle, the said operator at the same time driving anddirecting the animal moving the device through the field.

In the drawings, Figure 1 is an elevation of the devices formingmyinvention with one wheel of the vehicle removed, so that the parts maybe readily seen. Fig. 2 is a plan of the said device with thewater-barrel and seat removed, the shafts being broken. Fig. 3 is anelevation and partial section, in exaggerated size, showing theoperation of the pump and the adjacent and connected parts; and Figs; 4to 12, inclusive, show details or" devices more particularly hereinafterdescribed.

The wheels dare inoun ted upon the axle Z), and auframe composed of thelongitudinal members 1 and the transverse members 3, 4, and 5, with theshort end pieces G and 7, all

connected together and to the axle Z2, serve as a platform for carryingthe various parts of the mechanism and also to attach thereto therespective ends of the shafts c c and the whiffietree CZ, so as toprovide fordrawing about the vehicle. v The seat-support bar is shown at2.

The water-barrel c is sup-ported upon the frame in any desired manner. Ihave shown 6p a bracket-support S therefor, and a pipe c'. leads fromthe barrel e to the pump f. A pipe f leads from the pump to anair-chamberg, and a pipe g extends from the airy chamber g to and underthe receptacle h, holding paris-green or other poisonous material, andtherefrom this pipe g extends forward to the T-head 9, from which extendflexible branches 10 1l, that reach to the forward part of the vehicleand connect with the coup- 7o ling-heads c" 07. In the pipe g is a cock12, by which the llow ofy the liquid is regulated and may be cut od whenturning or passing from field to field.

Upon the axle o there is a disk 71;, having 75 equidistant studs 13, anda bar Z, placed approximately vertical, is connected near its upper end'to the pump-beam Z', lwhich extends towardthe back of the vehiclev andis' pivoted to a standard Z2 upon a platform 15, 8o supported by theframework of the vehicle. Upon the pivot connecting the beam Z to thestandard Z2 is a yoke m, straddlin g the beam and provided with aset-screw 14, bearing upon the top edge of the beam, and springs m areconnected. at their upper ends to the lower ends of the said yoke and attheir lower ends to a bolt 16, passing through the platform 15, the saidsprings acting to pull down the pump-beam Z', and the set-screws 9o 14serving to strain and apply tension to the springs m. .The saidpump-beam is elevated by the lower end of the bar Z coming in contactwith the studs 13 of the disk 7c by therotation of the axle of thevehicle, and with the up-anddown movement of the pump-beam the plunger f2 is operated to force the water drawn from the vessel c into theair-chamber g, in which a pressure is created to force the Water throughthe pipe g beneath the receproo tacle 7L and forward toward the sprayingdevlces.

lthe said studs 13.

A bracket 17 projects fromand is integral with the bar Z and connectswith a beam fn, placed parallel with but lower `than the pumpbeam Z',and while the bar Z is pivoted to the pump-beam the bracket 17connects'the bar Z rigidly with the beam n, and at the rear end o't' thebeam there is a hook device n', and the rear end of this beam n passesthrough a slotted standard n2, supported upon the platform 15, whichstandard acts as a guide to the bar Z and beam n as the same areoperated by the studs 13, and the special oflce of the said parts is todraw the bar Z away from the studs 13 of the disk 7c through the slot ofthe standard n2, the said bar Z being swung on its pivotal connectionwith the pump-beam into the position shown in Fig. 3 by dotted lines,where the hook has been turned over the top of the slotted standard n2,so as to hold back the said bar Z out of contact With In this positionthe pump is out of operation, while the vehicle may be moved from placeto place for service.

In the receptacle Zt is a plunger 18, having a vertical stem carrying aweight 19. These are readily moved out of the receptacle for theinsertion of paris-green or other poisonons material, and a short pipe40 connects with the lower part of the receptacle h, and in this pipe isa cock to control the amount of paris-green or similar material ejectedfrom the receptacle into the pipe g', to which the pipe 2O is connectedby a usual coupling. In View of the diiliculties attending the use ofparisgreen in the form of dry powder I prefer to employ a paste orBordeaux mixture of paris-green, as this readily disperses andcommingles with the liquid andl can be easily forced out of thereceptacle into the water.

The spraying devices are alike at either side of the machine, and assimilar characters of reference have been placed on corresponding partsthe description of one will suflice for the description of the other.The spraying-nozzles 20 21 are connected to flexible pipes 22 23,extending to the coupling-heads o and Z', between and connected to whichare the pipes 0. Arms r r are secured by bolts 24 to the part 5 of theframe, and swivel couplers s s' receive the free ends of the arms rr',These swivel-couplers are shown especially in Fig. 12, and they are ofpeculiar form and connected by the bolts 25 and adapted to turn at theirmeeting faces in relation to o'n'e another. Through the part s of thecoupler the pipes o' pass, and set-screws 26 27 serve to clamp the armsandpipes to the couplers, so as to adj us'tably fix the relation of theparts. The couplers s can be moved along the arms r r' when theset-screws 2G are loosened, and when the set-screws 27 are loosened thepipes o can be moved through the couplers s to adjust the position ofthe spraying-nozzles.

The feet of the driver or attendant are placed upon the platforms Z,which platforms are connected to pivot-shafts 28, secured to the frameof the machine, the said pivotshafts having cranks 29, from which extendthe rods 30 toward the forward part of the machine, the free ends of thesaid rods having a yoke 31 straddling the pipes o', as Will be seenespecially in Figs. 8, 9, and 10.

The spraying-nozzles 2O 2l are connected by pivoted rods 32 to thecoupling-heads o and i', so that the fiexible pipes 22 and 23 will notbend or be strained by the weight of the spraying-nozzles, these rods 32acting to hold the spraying-nozzles either at right angles to the pipeso or, when so placed, at acute or obtuse angles to said pipe, accordingto the direction that it is desired the spraying liquid shall take.

Straps 33 on the under side of the shafts pass around the arms rr', soas to 'support the said arms forward of their pivots 24 and hold thesaid arms in substantially a xed position, and in the operation of thesprayers the pipes o', with the spraying-nozzles on the respective endsthereof,are swung at the swivelcouplers s s by the foot of the operatorpressing either down at the heel or down at the toe upon the platformst, thus moving the' pivot-shafts 28, cranks 29, and rods 30, so as tomove the said shafts either in one direction or the other upon theswivel-couplers. It isnecessary to provide this movement, as Well as thepossibility of changing the angular relation of the spraying-nozzles tothe pipes o',so as to accommodate the device to the variable widths ofthe rows of potato-vines or other plants upon which t-he liquid-sprayeracts.

In my improvement the beam n and the bar Zare to be placed in theposition shown in dotted lines in Fig. 3, Where the hook 1t is caughtover the slotted standard n2, and in this Way the mechanism is thrown'out of action while the liquid-sprayer is moved from a place of storageto the field where` the same is to be actively employed in sprayingplants. The operator or attendant upon the seat of the machine (shown inFig. 1) may place these parts out of action. The parts are thrown intoaction by disengaging the hook from the plate and bringing the partsinto the position shown by full lines, Fig. 3, where the rotation of theaxle l?, the disk 7c, and studs 13 raise the bar Z to elevate thepump-plunger, the same being brought d'ow'n by the action of the springsm.

The operatorwith his feet upon the platformsLashereinbeforedescribed, isto change the inclination of the pipes o' and at the same time of thesprayers, and the inclination of the sprayers with reference to thepipes o is made by hand, so that between the operations the sprinklersare properly set for the widths of the rows of plants, andin theoperation of the device the supply of liquid to the sprayers iscontrolled by the extent of discharge by the sprayingnozzles 20 2l. Acertain amount of ,resistance is of course produced at these nozzles inthe discharge of the liquid IOO IIO

laden with paris-green lor other poisonous material and a back pressureis of course prof duced, and this is manifest both in the airchamber andin the pump, and where there is that back pressure the pump onlyoperates in proportion, because while the bar Z is raised its fullheight by the rotation of the disk 7c and the studs 13 the springs monly draw the pump-beam down to a point where their force and thepressure are equal. Consequently only a slight movement may be given tothe pump-beam. It is preferable to fix the angle at which the pipes omay be set, and this is done by the operator moving the parts at theswivel-couplers, and at the same time the rods 32 are moved on theirpivots to change the angle of the spraying-nozzles to the pipes o'.

It is obvious that other pressure devices may be employed in connectionwith the receptacle 7i for paris-green or other similar material insteadof the weight'li), but these would be equivalent devices.

IIeretofore the paris-green has been mixed in `the water-barrel c withthe water and h as been drawn therefrom. This may be done in the presentcase, although I prefer the other devices, and where the same is done Iemploy a chain 34E and stirrers 35 in the barrel, as shown by dottedlines, so that the stirrers keep the water and poisonous materialagitated in the barrel as the spraying devices are moved over theground, there being va sprocket on the axle and a short shaft passingthrough the barrel also carrying a sprocket and the said stirrers.

In Fig. 5 I have clearlyillustrated the Water connections between thebarrel, pump, aircylinder, receptacle h, and the pipe extendingtherefrom, and it will be noticed that the opening from the pipe e intothe pump is central of the pump and that. the opening therefrom to theair-cylinder is adjacent to one edge and that theopening into theair-cylinderiscentral and that the pipe g', extending therefrom andbeneath the receptacle h, comes above the opening into the air-cylinder,and in Fig. 6 I have represented the packing and valve, preferably ofsuch material as leather, forming a joint between the platform l5 andthe iianged base of the pump, this packing having a circular slot, asshown in Fig. 6, leaving in the center the valve-flap and having abovethe same a notch fitting around the exit from the pump to theair-cylinder, and in Fig. 7 Ihave shown the packing and valve of theair-cylinder with the valve-nap in the center adapted to cover thecentral iulet-opening.
